Pryor ran an attack ad against Cotton this summer that spotlighted the Ebola crisis

Is the President doing a good job handling the Ebola crisis? That's one question the Democratic senator running for reelection in Arkansas said is hard to answer.

When faced with the question, Sen. Mark Pryor couldn't come up with an answer because, well, "it's hard to know."

"Umm ... I would say that ... it's hard to know, uh, because I haven't heard the latest briefing on that to know all the details -- I mean, I read the paper and all, but," Pryor said in an interview that aired Tuesday on MSNBC.

Pryor, who is locked in a tight contest this fall, said he is of course aware of the efforts by the Centers for Disease Control and Prevention to contain the virus and the efforts of medical and engineering professionals fighting Ebola in West Africa.
